, Taal! wwm it may concern:

Be it known that I, WILLIAM JoIrN HAS- 'rINcs BEACH, subject of-thevKing of Great- B'rit'ain, residing at Wellington, 1n the Dominion of New Zealand, have invented a f new and useful Improved Aeroplane; and I do hereby declare the following to be a full, clear, and exact description of the same.

This invention relates to an improved constructipn of aeroplanethat has been designed with the view of obtaining the greatest amount of lifting power with a minimumof wind resistance, and generally the frame, and to the combination with each` of the main planes of ilexibly hinged eXten- 'sions that normally incline rearward from the back edge of the plane.

In fully describing -the invention, reference will be made to the accompanying sheet o f drawings, in which 'Figure l is-a plan of the machine. Fig. 2 is a side elevation thereof. Fig. 3 is a front elevation. Fig. 4 a plan of the frame and the small planes.- Fig. 5 a detail view on anenlarged scale of the frame work of one end of the main plane. elevationof the machine frame.

In carrying out the invention the frame is made up of a number of triangular members a arranged vertically parallel to each other and securely connected together by means'of tie bars or girders b extending along between their apexes and the extremities of their bases, such girders thus extending from front to rear of the frame. A stable fra-Ine is thus provided.

The main planes c are arranged to' extend transversely across the upper portion of thev frame, one at the front and the other at the rear thereof. These planes are made of suitable width and length and are adjusted to extend equally' upon both sides ofthe frame'.

.movement but in a reverse direction.

Fig. 6 is a side' Eachplane c is provided at its extremities with tips or ailerons yal hinged thereto in such a manner as to be capable of turning u p or down to assume varying angles with the surface of the plane.- These several ailerons are connected together so as to work.

in conjunction with each other so that the two on one side of the machine will turn down or up to ether, while the two on the other side will e given an equal amount of These connections are not shown in the drawings V as this feature is one well knownin connection with t-he construction 'of other aeroplanes and' forms no feature of the present invention. vided with a pair of rearwardly extending Each main plane is also prowings e arranged one on each side of the machine frame and hinged to the rear edge of the plane. These wings are hingedand acted on by springs e (Fig. 5) in such a manner that the ward at a slight incline, as shown in 2. The springs are so adjusted in tension that when the machinei's passing through the air ata high speed the air lpressure beneath the wings will force them up so that they will extend uniformly'with the surfaces'of the planes. Then when the speed is reduced or the flightof the -machine is stopped, these wings under the action of their springs, w resume their normal inclined positlon so normally extend down?-y that they will impart an elevating tendency to the pla-nes and thereby prevent the Inachine diving straight down to the ground,-

but instead, lwill cause it to glide down at an incline in order that it may settle on it' Deiecting planes f and g are seen. at the front and one at the rear of t chine, such planes Ibeing ofthe well knowntype in construction-and operation and be'- ing worked together in the well known way. These planes are used for guiding the achine up or down in its fi-ights the connections hetween the planes being such that whenthe front, plane is turned up, the rear plane will'be turned down a corresponding amount and vice versa` The machine is also rovided with the rudder 7|. at its rear, suc

rudder being to control its flight in'the horizontal plane and i being also a with the ailerons din the well known manner by means of suitablen connections not shown in. the drawings. 'i

A small subsidiary supporting plate j is apted to Workin conjunction.

" above the 'rear small vplane j. Any passe n. gers or weight carried on the machlne will' secured across the bottom of the frame beneath each main plane. These planes j'are made shorter than the main planes so as to permit the; air to have free access to the main planes and thus not to interfere with the buoyancy thereof. The planes serve'to assist in 'c rrying the weight of the frame andiofthelriving engine and' aviator.

A prope er is is mounted in front of each main plane and is secured upon a shaft Z carried in bearings upon the frame. The two shafts and their propellers are adapted to be driven from the engine or motor carried upon the forward plane y' and are lchine when it alights'on to the ground.

The 4motor will preferably be arranged above the forward small plane j while the seat for the aviator and the several Fcontrolling levers and Wheels will be arranged then be placed along the frame between them so lthat the whole weight carried will thus beevenly distributed throughout the full lengthof the machine.

It will be seen that the main weight of the machine is all arranged beneath the -main planes thereof so that its stability and capability to keep on an even keel while in Hight, will be materially assisted.

What I do claim as my invention, and desire to secure by Letters Patent is z- 1. In aeroplanes, a frame composed of a `number of triangular members arranged vertically parallel and having horizontal bottom bases and connected together b'y tie bars-extending along their apexes and bases, two main planes secured across the upper part of such frame, on'e`behind'the other a subsidiary short plane secured across the bottom ofthe frame beneath each main plane, level with said bases and a separate propeller for each of such main planes, sub stantially as specified.

2. AIn aeroplanes, a frame composed of a number of triangular members arranged vertically parallel and connected together by tie bars extending along their vapeXes and bases, two main planes secured across the upper part of such frame one behind the other, laterally extending hinged wings or ailerons on both ends of each main plane, a pair of rearwardly extending hinged Wings on each plane, springs for normally holding such wings at a downward incline,

andy a separate propeller for each plane,

substantially as specified,

In testimonywhereof, I have signed this specification in the presence of two subscribing witnesses.
